An "easter egg" is code deliberately hidden in the code, both from
potential users and even from other developers. This lint check looks
for code which looks like it may be hidden from sight.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
src/test/pkg/Hidden.java:5:Warning: Code might be hidden here; found
unicode escape sequence which is interpreted as comment end, compiled
code follows [EasterEgg]
    /* \u002a\u002f static { System.out.println("I'm executed on class load"); } \u002f\u002a */
       ------------
src/test/pkg/Hidden.java:6:Warning: Code might be hidden here; found
unicode escape sequence which is interpreted as comment end, compiled
code follows [EasterEgg]
    /* \u002A\U002F static { System.out.println("I'm executed on class load"); } \u002f\u002a */
       ------------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is the source file referenced above:

`src/test/pkg/Hidden.java`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~java linenumbers
package test.pkg;

public class Hidden {
    // Innocent comment...?
    /* \u002a\u002f static { System.out.println("I'm executed on class load"); } \u002f\u002a */
    /* \u002A\U002F static { System.out.println("I'm executed on class load"); } \u002f\u002a */
    /* Normal \\u002A\U002F */ // OK
    static {
        String s = "\u002a\u002f"; // OK
    }
    // STOPSHIP
    /* We must STOPSHIP! */
    String x = "STOPSHIP"; // OK
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[source code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/CommentDetectorTest.java)
for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test
found for this lint check, `CommentDetector.testJava`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Using a suppression annotation like this on the enclosing
  element:

  ```kt
  // Kotlin
  @Suppress("EasterEgg")
  fun method() {
     TODO(...)
  }
  ```

  or

  ```java
  // Java
  @SuppressWarnings("EasterEgg")
  void method() {
     TODO(...);
  }
  ```

* Using a suppression comment like this on the line above:

  ```kt
  //noinspection EasterEgg
  problematicStatement()
  ```

* Adding the suppression attribute `tools:ignore="EasterEgg"` on the
  problematic XML element (or one of its enclosing elements). You may
  also need to add the following namespace declaration on the root
  element in the XML file if it's not already there:
  `xmlns:tools="http://schemas.android.com/tools"`.

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="EasterEgg" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'EasterEgg'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore EasterEgg ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
